Do you have imagine broadband up around where you live? We have it and it's pretty good - no city speeds like, and the VOIP landline is pretty flaky, but the internet is a zillion times faster than it was when we were going via eir (right now it's 139Mbps down, 3.89Mbps up, but it's very variable)
We are not wired so regardless of company we are limited essentially by line of sight with a mast in the city. I did some slog on trying to improve things early in lockdown and was offered the moon, only to get to mid call person saying 'eh well we can't actually guarantee any speed increase'. Essentially if two trucks go down the motorway back to back i can actually see it on a speed guage.
